Title: Checking device for checking times of attendances
Inventor: TONNE F
IPC: G07C1/10
Filed: 1969-10-24
Abstract: 1284462 Time recorder for workmen F TONNE 24 Oct 1969 [16 Nov 1968] 52123/69 Heading G4T A device for checking the times of attendances of a plurality of workmen comprises for each workman a counter 4 with an operating switch 1A whereby the counter is switched on and off at the beginning and end, respectively, of a working period. A blocking device 20 switches off any counter that has not been switched off by a predetermined time of day. The switches may be operated by keys, coded cards, or codes entered into an electric matrix; each counter operates over a complete pay period (week or month). As described, at the start of a working period a workman closes an associated switch 1A with a key 2A thereby connecting an impulse emitter 5, working at 100 pulses per hour, to an appropriate impulse counter 4. At the end of the working period the key 2A is used to reopen switch 1A and disconnect counter 4. A blocking device 20 comprising a switch bridge 22 and a polarized relay 21 (or non-polarized relay, bistable transistor switch circuit, electric melting fuse, or thermal switch-off mechanism) is actuated by the pulse from a timer 24 at a predetermined time such as midnight, if the workman has forgotten to reopen the switch 1A. The pulse actuates the relay 21 to switch over the bridge 22, disconnect counter 4, and energize a lamp 30. The counter 4 cannot be reconnected by the key 2A until the blocking device 20 has been returned to its original state by a pulse from a network 8 via a locked switch 26 located at a control centre. Relay 21 is protected against unauthorized manipulation. Any excess pulses are deducted from the counter 4 by the control centre. In an alternative embodiment (Fig. 2, not shown) a time clock (9) is provided to disconnect the counters 4 during work breaks within a working period. A multi-channel tape recorder (7) records the positions of the switches 1A- 1C; a lamp (11) is connected in parallel with each tape channel (6) to indicate to a telephone exchange, the presence of each workman. The switches 1A-1C, counters 4, and a set of absence-indicating lamps (3) are mounted on control boards (10) placed at several convenient locations in a factory. In a third embodiment (Fig. 3, not shown) extra counters (41-43) are provided for each workman for recording the times of individual jobs. Further counters (44) and (40) record respectively time beyond a certain pay period, and the cost of the job.

Heading [Also in Divisions D1 and G1] A circuit giving an output proportional to the logarithm of a light intensity comprises a photovoltaic cell or photo-diode 4, Fig. 1, connected so as to tend to cut off the conduction of a transistor 1. The transistor is maintained conducting by a bias applied from the D.C. source 3 through a diode 5 having an exponential characteristic. Any variation of current from the cell 4 causes a negative feedback through diode 5 with the result that the output has the required logarithmic relationship with the light intensity. The circuit may be adapted to a PNP transistor, Fig. 2 (not shown). The circuit may respond to variations in the thickness of running yarn, Fig. 3 (not shown), the output being applied through an amplifier and a threshold circuit to a mono-stable multivibrator 12, 13 controlling a magnetically operated yarn cutter.
